MATERIAL-MOVING APPARATUS.

Specification of Letters Patent.

Patented Nov. 13, 1917.

Application filed May 14, 1917. Se ial No. 168,463.

To all whom it may concern:

Be it known that I, HENRY B. SAUERMAN, a citizen the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Material-Moving Apparatus, ofwhich the following is a specification.

My invention relates to improvement in material-moving apparatus of thetype comprising, generally stated. an inclined guideway supporting atraveling carriage thereon wth a dumping scraper-bucket connected withthe carriage, and a hauling-line through the medium of which themovements of'the carriage and bucket are controlled, my object being toprovide a novel, 's'mple and positively operating construction of thisgeneral type, in wh ch the bucket is prevented from accidentallyswinging to dumping position in the movement of the bucket to dumpingposition. 7

Referring to the accompanying draw:- ings: a

Figure 1 is a view in side elevation of apparatus constructed inaccordance wth my invention for transferring material from one elevat onto a higher elevation, the apparatus being shown in the position itassumes in moving to dumping position. Fig. 2 is a section taken at theline 2 on Fig. 1 and viewed in the direction of the arrow. Fig. 8 is aview like Fig. 1, showing the parts of the apparatus in dumpingposition. Fig. 4 is a view like F g. 1 of another embodiment of myinvention. Fig. 5 isa section taken at the line 5 on Fig. 1 and viewedin the direction of the arrow. Fig. (i is a section taken at the line 6on Fig. 1 and viewed in the direct on of the arrow and Fig. 7, a viewlike Fig. 1 of still another embodiment of my invention. i

In all of the constructions illustrated I have shown my invention asincorporated in a so-callecl slack-line system the inclined cable-way ofwh ch is represented at 8 and in practce wouldbe anchored at its lowerend in any suitable manner, and at its upper end supported at a higherelevation and ma manner adapting it to be slackened and made taut atwill, all as is well'understood in the art and therefore does notrequire illustration. r

Referring-more particularly to Figs. 1, 2

and 3. 9 1 IS a carriage which "slidably mounted on the cableway 8 andin the'forno shown comprises a pair of plates 10 and and 11 are groovedpulleys 14 journaled on certain of the bolts 12 and by wh ch thecarriage engages the cable-way -8. The dumping scraper, or bucket,represented at 15 and which is'supported from the carrings 9, is ot'aform generally employed its forward, open, digging-end 16 being providedwith an edge-portion 17 in practice usually serrated. The bucket 15 iscon nected at its rear endas at'eyes 18 at oppos te sides of the bucketwith chains or cables 19 oneonlyof wh ch is shown,-which connectat theirupperends w'th eyes 20 on the carriage, whereby the bucket is, ineffect, pivotally hung from the carriage 9 and at such a point relativeto'its center of gravity that the latter will tend normally to swing todumping pos'tion. The-bucket 15 is connected at its front end with abranch 21 of the hauling-line in the fcrm'of a bridle, which unites w thanother branch 22 thereof at a block 23 connecting withthe singlesection 24 of the hauling-line. Thebucket is also connected at a bail 25thereon, with a cable 26 in the form of a bridle, which connects at itsupper end as ind'cated at 27 with pivoted eyes 28 on a rock-member 28located between the plates 10 and 11 and pivoted on the lower bolt 12,

the rear end of the branch 22 running over a pulley 29' journaledbetween the plates 10 and 11, and connecting with the member 28 adjacentthe connection 27. The m'ember28 is provided with a projection 80 whichin the load-carrying postion of the apparatus rests against a'pin 31extending at its ends in curved slots 32 in the plates 10 and-ll andmovable up and down therein, the pin 31ypassing through a yoke 33located between the plates 10 and 11 and connected at its upper end witha cable 3 1' which passes over a pulley 35 on the carrag'e,

thence over'a pulley 36 on the block 23 and connects with a travelingblock 37 running, at a pulley 38 thereon, on the cable-way 8',thisblockcooperating with a stop 39, prefa purpose hereinafterdescribed.

Theparts of the apparatus are-so con-- erably adjustable along thecable-Way 8,"for V shown in Fig. 1, thus normally holding the bucket inload-carrying position and the bucket cannot swing to dumping positionuntil the member 28 has been rocked to carry the cable 26 forward ofsaid pivot.

In the operation of the apparatus the bucket is dragged along thematerial to be moved, by drawing on the hauling-line and the carriagepulled along the cable-way 8 to the point of dumping. When the block 37strikes the stop 39 the block 37 is arrested and continued movement ofthe hauling-line will operate to raise the yoke 33 and with it the pin31 which rocksthe member 28 m a in this figure, thus returning theseparts to.

normal position.

Itwill therefore be understood from the foregoing that during themovement of the bucket along the cable-way 8 from filling to dumpingposition, the bucket is held against dumping even should the haulinglinebecome slack.

The arrangement shown in Figs. at, 5 and Sis the same as that shown inthe preceding figures excepting for the mechanism which rocks the memberIn this arrangement the member 28 carries a pin 40 adapted, in thenormal position of the parts, to abut against/the forward'cdges of thecarriage (Fig. 4-), the, cable 26 connecting with collarsllrotatableonthe pin FL-and the cable 22 connecting with i the member28. The pi-n-tOccoiiperateswith a latch-device -12- which is preferablyformed; ofv a. forked member43, pivoted ;atll- -on a block supported, atpulleys ti on. the cable and anchoredbya cabled? toa bloc zk4 8 sta;tionary onthe cable-way, 8, th'e pur1: ose of this cable connectionbeing to permit. the block-45 and latch-43, to; give upwardly to aslight-degree when struck, by the pin i-O as-hereafter described.Thelatch member 43..which is. held in the position shown in Fig. 4 byachain 49, hasshoulders ad? jacentcam-surfaces; 51i which extend in thepath of movement; oi"; the pin 1 40 when the carriage 1 ismoved tobucket discharging po si-tion, and by. engagement ot-,-th e pin.; 49

In

the normal position of the member 28 it rests against a pin 53 whichextends at its ends carrying washers beyond theplates 10 and 11, intoregistering arc-shaped slots 55 in the side plates one only of theseslots being shown, this pin extending clear through the carriage andbeing so disposer, that it may be bodily lifted in the register:ingslots and in this movement, by engaging the projection swinging themember 28 in clockwise direction in Fig. 7. The opposite ends of the pincooperate with levers 56 which are pivoted at 57 to extend at oppositesides of the carriage and engage at their lower ends beneath the ends ofthe pin 53, these levers preferably being of bent form as illustratedand connected together at their left-hand ends in Fig. 7, which arepreferably spaced apart by a cross-bar 58. The levers 58 cooperate witha lever-trippingdevice 59 secured to the cable-way8 at substantiallythepoint at which dumping is to be elfected, this device presenting aninclined camming surface 6O against which the pin 58 moves and in whichmovement the levers 56 are rocked in an anti-clockwise di} rection inFig. 7 to force thepin 53 'upwardlyin the slots and rotate the mem ber-28. The camming surface prefe erably providedas the under-surface abar 61 pivotally connected at 62 with a. block 63 secured to thecable-way,8 the free end of this lever being connected with a cable tiitde aending "from the block 63. The lever should be heavy enough to causethe member 28. to, be rotated in a clockwise direction in Fig. 7 againstthe resistance of the weight tendingto prevent such rotation, the provision of the surface 60,. as a part of aswinging lever being for.thepurpose of providing a y ld ng ann n were; e, P'r Y i shock.

Theinormal loadcarnyina...nosition of the rei'n.

ment of the pin 58 with the lever 61rocks the member 28 to a positionin'which the cable 26 extends forward of the pivot of the member 28,,whereupon the bucket 15 drops by gravity to dumping position. Upon againdrawing the hauling-line taut, the connection of the branch 22 with themember 28 returns the latter to normal position (Fig. 7) and likewisereturns the pin 53 and levers 56 to the position shown in this figure.

It will be understood from the foregoing description of the structuresillustrated that in each of them provision is made for preventing thebucket from swinging to dump 'ing position should the hauling-linebecome slackened before the bucket reaches the point of dumping, andthat in the operation of drawing the hauling-line taut after the dumpingoperation has been efi'ected, the means which hold the bucket inloadcarrying position against accidental dumpingthrough the slackeningof the haulinglinc, are returned automatically to normal operatingposition.

lVhile I have illustrated and described certain forms in which myinvention may be embodied, I do not wish to be understood as intendingto limit my invention thereto,

as altered without departing tromthe spirit of my invention, it being'myintention to claim my invention as fully and completely as the priorstate of the art will permit.
